Ruledle

Ruledle turns the old party game where one person knows a secret rule into a solo daily puzzle. Each day has one rule that decides every answer. The game shows a sequence, for example five digits, and asks a question with two answers, such as Border or Center or, on 22 October 2026, Ripple or Settle for rows of fruit and flower emoji. You pick one and learn whether it was right, and every sequence goes into a review list with its correct answer so you can compare them.

To win you need five correct answers in a row; a single mistake sets the count back to zero, and you have ten guesses for the day. The rules use everyday observation rather than trivia or heavy maths: the count of symbols is even, the last digit is 5 or more, the word has a double letter, the word starts with a vowel. The question type changes from day to day.

A new puzzle is released every calendar day in UTC, numbered and dated, and everyone plays the same one. The archive keeps every earlier day and shows how many players solved it and whether it played easy, moderate or hard. Ruledle is free with no account, saves progress on your device and is available in 33 languages, from Spanish and Hindi to Japanese and Greek.

It suits players who like deduction puzzles such as Clues by Sam or Deduce and enjoy the moment a pattern clicks.
